PARQUETRY.

SPECIFICATION forming part of Letters Patent N0. 457,788, dated August18, 1891.

Application filed January 8I 1891. Serial No. 377,079. (No model.)

To all whom it may concern:

Be it known that I, GEORGE Ross MCKEN- ZIE, cabinet-maker,a subject ofthe Queen of Great Britain, residing at 57 Willes Road, Kentish Town,London, in the county of Middlesex, England, have invented a certain newand useful Parquet, of which the following is a specification.

Parquet when fixed on damp or shifting foundations is very liable towarp, and this is not avoided by using a canvas or wood backing, becausethe backing itself warps, and the cement by which it is iixed is liableto give way. According to this invention I use a backing which iswater-proof and unstretchable, and I fix it in a special manner hto thefoundation, such as a floor or wall.

Preferablyl use perforated metal with the holes filled up withWaterproof cement or else the material known as patent roofing, whichconsists of a wire net-work embedded in water-proof paper. I attach thewood to thebacking bynailsor screwsinserted through the backing, aidedby cement. I make such work in lengths, with the backing projectingbeyond the wood on one or more sides, so that the backing can be fixedto the founda-V tion by nails or screws through the projecting edge. Theedges of the pieces or lengths of parquet are secured together by metaltongues.

Figure 1 is a plan of two pieces of parquet. Fig. 2 is asection on thelines a: Figs. 1 and 3; and Fig. 3 is an under side view.

ct a are the usual pieces of board or veneer of which the surface of theparquet is composed.

b b isa backing of perforated metal. In Fig. 3 the perforations are onlyshown in one corner. The wood is secured to the backing.

dation by screws d d; but the right-hand piece is unfastened and is notquite in position for fixing. When in place, the lefthand edges (itswood and metal, respectively) will abut against the right-hand edges ofthe wood and metal of the other piece.

e is a metal key which enters into slots f in the edges of the wood andholds the two pieces together. NVhen fixing this parquet to a floor orother surface, the projecting metal of'the outer pieces or lengths arecovered by fillets of wood.

What I claim is 1. Parquet consisting of anumberot pieces of wood fixedupon a sheet of backing projecting beyond the edge of the wood on one ormore'sides and stopping short of it on another or others.

2. Parquet-work having the parquet made in sheets or lengths, eachconsisting of a number of pieces of Wood xed upon a sheet of backingprojecting beyond the edge of the wood on one or more sides and stoppingshort of it on another or others, the projecting edges of the backingbeing secured to a foundation by means of nails or screws.

London, December 17, 1890.
